Crystals

Crystals are highly ordered structures that exhibit predictable electrical and physical properties and are integral components of many industries. Electronics and communication applications rely on them to precisely generate, capture and filter signals. Manufacturing applications use them to regulate frequency, synchronization and timing. Automotive, medical and defense uses also benefit from the simplicity of these hardy devices.

ATS22A-E Application Field and Working Principle

The ATS22A-E is a quartz crystal unit designed to generate accurate sinusoidal signals with high frequency stability. It is a compact, high-performance option that is ideal for consumer electronics and communication usages. The core element of the ATS22A-E is a button quartz crystal that is AT-cut, which allows for optimum frequency stability, low cost and superior reliability. It comes in two main types, oven-controlled and temperature-compensated, depending on the application.

The ATS22A-E is a dual-in-line ceramic package, which contains a quartz crystal and two electrodes. It has a tiny pre-stressed vibrator connected to the package via a pair of pads. The vibrator has a wide range of cutoffs, allowing frequencies of up to 50 MHz. The overall size of the package is small, allowing for integration in space-limited applications.

The working principle of ATS22A-E is based on the quartz crystalline effect. Quartz crystals have a naturally capacitive-resistive property, which is known to have extremely high frequency stability. When a high voltage is applied to the electrodes of the package, a resonant oscillation is generated and maintained by a “piezoelectric effect” on the quartz crystal. This oscillation is then translated through the package to create a stable output.

As a result, the ATS22A-E generates a precise and stable sinusoid signal that is suitable for a wide range of electronics and communication applications. It is especially suitable for precision frequency control and reference applications, including clocks, timing devices, wireless systems, imaging systems, navigation systems and medical equipment.

In addition, the ATS22A-E is renowned for its robustness and longevity, and can operate in an ambient temperature range of 0-60°C, with a maximum vibration proof up to 100G (non-operational vibration) and 10G (operational vibration). This makes it particularly suitable for harsh environments, such as manufacturing testing and industrial automation.

As a result, the ATS22A-E is an ideal choice for anyone seeking a precise and reliable quartz crystal unit.
